WILLIAM P. DUN LANY, OF MAYWOOD, ILLINOIS, ASSIGNOR TO GHARIIES W. SHONK COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

GOIN-CHANGEJIAKING MACHINE.

Specification of Letters Patent.

Patented Nov. 12, 1918.

Application filed July 18, 1913. Serial No. 779,663.

To all whom it may concern Be it known that I, W'ILLIAM P. DUN Larry, a citizen of the United States, residing in Maywcod, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Coin-Change-Making Machines, of which the following is a specification.

This invention relates to improvements in coin change-making machines.

One object of the invention is to provide ,a coin change-making machine which is cheap in first cost; is composed of relatively few parts simply arranged; and which is adapted to have most of its parts stamped up from sheet metal.

Another object of the invention is to provide a change-making machine which has automatically-operated devices for locking the parts when any of the coin reservoirs are empty and there are not enough coins to make the desired amount of change.

Another object of the invention is to provide a coin change-making machine having an attachment for giving the desired amounts of change in pennies.

The invention furthermore consists in the improvements of the parts and devices and in the novel combinations of the parts and devices as herein shown, described and claimed.

In the drawing forming a part of this specification, Figure 1 is a top plan view of a. machine embodying my improvements. Fig. 2 is a front elevation of the structure shown in Fig. 1. Fig. 3 is transverse, vertical section taken substantially on the line 33 of F 1. Fig. 4 is a similar section taken on the line H of Fig. 1. Fig. 5 is a sectional view taken substantially on the line 55 of Fig. 8. Fig. 6 is a sectional view taken substantially on the line 66 of Fig. 5. Fig. 7 is a detail, part plan, part section, of parts within the casing of the machine. Figs. 8 to 15, inclusive, are detail views of the various keys or levers, including those for obtaining change in amounts varying in steps of five cents from 10 to 45. Figs. 16 and 17 are detail views of actuating-slide levers which cooperate with the and keys, respectively. Fig. 18 is a detail sectional view taken substantially on the line 1818 of Fig. 1 and shows more particularly the penny change-making device. Fig. 19 is a sectional view taken substantially on'the line-19 19 of Fig. 18, andFigs. 20 to 22, inclusive. are detail views of three of the penny ejecting-slides.

In said drawing the machine. as shown, includes a suitable casing or shell S adapted to support the various parts of the mechanism and having an inclined shelf or table T. The casing or shell S is also provided with a plurality of coin reservoirs U, V, W, X and Y adapted to hold stacks-of nickles, dimes, fifty-cent pieces, dimes and quarters, respectively, said reservoirs being slightly inclined from the vertical and open on their front sides to thereby facilitate the insertion therewithin of stacks of coins as will be understood. lVithin the shell at the front thereof and extending longitudinally, is an inclined chute Z, down which the coins, when ejected from the reservoirs, as hereinafter described, fall and are delivered to the operator on a shelf R. From the" preceding description it will be understood that the penny change-making attachment is not included, inasmuch as the same will be hereinafter separately described.

Mounted in the shell and extending longitudinally thereof is a shaft Q on which are pivotally mounted a plurality of actuating keys or levers 5, 10, 15, 20, 25, 30,35, 40, and corresponding, respectively, to the amounts of change which-is delivered when said keys are operated or depressed. Each of said actuating keys or levers, as most clearly shown in Figs'j3 and 4, is provided with a substantially U-shaped portion on the forward side of the shaft Q, the free ends of the U-shaped portions being provided with suitable finger keys or buttons having the proper amounts designated thereon. Each of said actuating keys or levers 5, 10, 15, 20, 25, 30, 35, 40 and 5. at the rear of the shaft Q, is provided with a notched yoke-lifting or actuating portion as will be hereinafter more particularly described. The actuating key or lever 50 difiers from the other keys, in that it'operates its corresponding coin ejecting-slide directly and doesnot operate any of the yokes about to be described. 1

Also pivotally mounted on the shaft Q and extending rearwardly therefrom are four yokes or bars A, B, C and D, so arranged that when in normal position they nest one within the other, as shown more particularly in Figs. 3 and 7. Also pivotally mounted on the shaft Q above the yokes A, B, C and D are four ejecting-slide operating levers 20, and 252 said ejecting-slide operating levers cooperatin respectively, with the actuating keys 5, 10, and 20, and 25. The actuating key or lever 50 for ejecting a fifty-cent piece is provided with an integral ejecting-slide operating lever 50 see Fig. 8. Each of the ejecting-slide operating levers 5% 10, and 50 is provided with a lug or proj ection 11 which engages in a slot formed in the corresponding ejecting-slides 5, 10 20", 25 and 50". These ejecting-slides are reciprocatingly mounted in suitable guideways 5, 10, 20, 25 and 50, respectively, see Fig. 6, and at their front ends are each provided with an arcuate recess for engaging the lower-most coin of the coin reservoir with which it cooperates and, as will be understood, the thicknesses of these ejecting slides approximate the thicknesses of the respective coins to be ejected. As shown in Fig. l, the stacks of coins rest upon the plates forming the guide-ways 5, 10, etc., the latter being also provided with arcuate recesses at their forward ends a short distance in front of the stacks of coins so that when the lower-most coins of the stacks are separated'or removed from the bottom of the stacks and pushed forward they will drop therethrough into the chute Z. Each ejecting-slide is normally held retracted or in its rear-most position by a retracting spring 12 suitably attached at one end to a fixed part of the shell or casing.

In order to prevent an incorrect amount of change to be delivered when a key is pressed should any of the coin reservoirs be empty, there are provided a plurality of pivoted levers 13, one for each reservoir and each having at its forward end in front of its correspondingreservoir, a depending cam l t, see Fig. t, which lies in the path of the lower-most coin of the stack. lVhen the corresponding ejecting-slide is advanced and there is a coin in the reservoir the latter will engage the cam 14 and thereby lift the lever 13. This operation in turn lifts a stop or flange 16 which normally lies in the path of the corresponding projection 11. When no coin is present in the reservoir from which a coin ought to be ejected to make the proper change, the corresponding lever 13 will not be operated and a full movement of the ejecting-slide operating levers will be prevented, thus automatically locking the machine and preventing a false amount of change being delivered.

1 will now describe the means for selecting the proper ejecting-slide operating levers when any of the keys 5, 10. 15. 20. 25, 30, 35, or are operated. Referring now to Fig. 4, it will be seen that the rear portion of the actuating key or lever 5 is provided with acut-out portion 5 which is of sufficient width to escape the yokes B, C and D when the key 5 is depressed, but a depression of the key 5 will lift the yoke A, which in turn engages the actuating lever 5 and thereby operates the ejecting-slide 5. It will also be noticed that the ejecting-slide actuating lever 5 is provided with a cut-out portion 5 of sufficient size to permit upward movement of the yokes B, C and D without the lever 5 being affected thereby. In like manner the rear portion of the actuating key or lever 10 is provided with two notches 10 which provide clearance for the yokes A, C and D when the key 10 is depressed, but the yoke B will be engaged and lifted, which in turn will engage and operate the ejecting-slide actuating lever 10 which is provided with a projection 10 resting upon the yoke B, see Fig. at. The lever 10 is also provided with recess or cut-out portions to provide clearance for the yokes A, C and D whenever the latter are actuated. From the preceding description it will be seen that when the key 10 is depressed, the ejecting-slide 10 will be operated thereby ejecting or cutting out a ten-cent piece from the stack of coins in the reservoir V. The key lever 15 is provided with two cut-out portions 15 arranged to clear or pass by the yokes B and D so that when the key 15 is depressed the yokes A and C will be shifted, thereby operating the levers 5 and 20 and causing the cutting out of a nickel from the stack in the reservoir U and a dime from the stack of coins in the reservoir X, it being understood that the ejecting slide actuating lever 20, see Fig. 16, is provided with recess or cut-out portions 20 so located that the same is not operated by a movement of any of the yokes A, B or D. Vhen the key 20 is depressed the rear por tion thereof will lift the yokes B and C, thereby operating the ejecting-slide actuating levers 10 and 20 and, as will be understood, the rear portion of the key 20 is provided with recesses or cut-out portions :20 which clear the yokes A and D to thereby prevent operation of the latter. lVhen the key 25 is depressed, the rear end thereof will engage and lift the yoke D only, which in turn will operate the ejecting-slide actuating lever 25 see Fig. 17, the latter in turn actuating slide 25" to thereby eject a twentyfive cent piece from the reservoir Y.

In order to obtain thirty cents in change, the rear portion of the key 30 is so designed that it will engage and lift the yokes A and D, thereby causing the cutting out of a five cent piece and a twenty-five cent piece. The rear portion of the key 35 is arranged to operate the yokes B and D, thereby ejecting a ten cent piece from the bottom of the sta-k in the reservoir V and a twenty-five cent piece from the stack of thus cutting out two ten cent pieces and a twenty-five cent piece. For obtaining fifty cents in change the rear portion. 50 of the key 50,,which is formed integral therewith, engages directly the ejectingslide 50 and no movement of any of the yokes A, B, C or Dtakes place. For obtaining amounts of change varying'from fifty-five cents to ninety-five centsby steps of five cents, the key 50 will alwaysbe operated inconjunction with thecorresponding key. 5, 10,15,20,

i .25,- 30-, 35, 4:0 or 45 in accordance with the amount of change desired. ,As for instance,

when sixty cents change is desired the keys 50 and 10 will be depressed, and for seventyfive cents the keys 50 and 2 i It will thus be seen that the finger key levers and ejecting levels are of key-like form on their opposing surfacesor edges, being variously provided wlth operat ng surfaces and inoperative escape recesses or cut-out portions, and constituting a simple means, eliminatlng much complication of mechanism, for ejecting coins in various combinations.

For obtaining change in pennies in amounts varying from one to. four cents, the attachment F is provided, which, as shown more particularly in Figs. 1, 2 and 18 to 22 inclusive, comprises a shell orcasing 21 having a reservoir 22 for holding a stack of pennies, the construction and arrangement of the reservoir 22 being similar to those forthefi, 10, 25 and 50 pieces. As shown in Fig. 18, the stack of pennies is adapted to rest on a' plate 23 on which are mounted four slides, 1 2 3 and P, the latter being actuated directly by actuating levers or keys 1, 2. 3 and 4, respectively. As will be understood, each ejecting-slide 1 2 3 and e corresponds in thickness to the thickness of a penny or cent piece so that a movement of the lower-most slide 1 will cut out one penny, a movement of the slide 2 will'cut out two pennies, etc. Each of the ejecting-slides 1 2 3 and 46 is provided with a retracting spring 26 to normally hold the slides in their rear-most position. Each of the actuating keys or levers 1,2,3 and 4 is provided with a projection 27 which engages in slots formed in the ejecting-slides; the slots being so arranged in the difierent slides that a movement of the key 1 will only operate the slide 1, a movement of the key 2 will operate the slides 1 and 2 the key 3 will operate the slides 1 2 and 3 and the key 4 will operate all four slides 1. 2, 8 and 4 The pennies, as ejected,

will fall onto an inclined chute'28 which directs the coins into the. main chute Z so that the pennies will be delivered onto the tableR. The penny change-making device F is readily attached to the shell or casing S by means of screws or other suitable devices 29.

From the receding description it will be seen that I ave provided a coin changemaking machine of relatively simple con struction, composed of few parts and adapt ed to make change in any amounts varying from one cent to ninety-nine cents, and having also automatically operated 111821115101 preventing an incorrect amount of change being delivered which does not include pen nies.

Although I have herein shown and described what I now consider the preferred embodiment of my improvements, yet it will be understood that various changes and modifications may be made in the details of construction and arrangementof parts without departing from the spirit of my invention, and all such changes and modifications are contemplated as fall within the scope of the claims appended hereto.
